About the Product

The secondary air injection system (PAIR) routes fresh air from the airbox to the exhaust system in order to aid the combustion of unburned fuel in the exhaust. This system is designed to improve emissions on stock exhaust systems, but will cause exhaust popping and backfiring when you fit aftermarket exhausts.
